This clock was created using a recycled Mac 15" Powerbook case, complete with Apple mouse utilized as the working pendulum bob. The clock measures 13.5"w x 17"h. These are made from retired Macs, and therefore will have signs of wear and tear, scratches, scuffs, etc. This one does have a few scratches and scuffs, as visible in the pics. It has a quartz clock/ pendulum movement and runs on 2 AA batteries, included. It makes a great conversation piece and will also make a great gift for that Mac geek you know who is so hard to shop for. Handmade in the USA. Thanks for looking.
